can if and history macros be used together? if so, how?

Question

Using Twine2, trying to get an if statement to tell whether one passage has been visited or not but I'm getting errors, what am I doing wrong? 

(if: (history: "Let's go gambling!"))[Well, that's kind of your fault for gambling the night away, isn't it?]
(else:)[I wonder why? Maybe in another life you gambled the night away and now I'm having flash backs to that life and I can't seem to get things straight. Sorry, my bad.]

Thank you

WARNING: I strongly suggest not using punctuation characters within the names of your Passages, as strange things can happen when you do. So I would rename your existing Let's go gambling! passage to something like Lets go gambling and then using a link like the following to access it.

[[Let's go gambling!->Lets go gambling]]

 

The (history:) macro returns an Array, and the Array data section of the guide explains how to use the contains operator to determine if a particular value is contained within the array.

(if: (history:) contains "Lets go gambling")[Well, that's kind of your fault for gambling the night away, isn't it?]\
(else:)[I wonder why? Maybe in another life you gambled the night away and now I'm having flash backs to that life and I can't seem to get things straight. Sorry, my bad.]

note: I made two addition changes to the above example:
a. I replaced the passage name being looked for with one without punctuation characters.
b. I added Escaped line break markup between the end of the (if:) and the start of the (else:) to suppress the unwanted line-break that was appearing if the (else:) related text was shown.

I did the changes you did but it says that it is an 'unexpected string' and has 'nothing before this (else:)'

Never mind, I figured out how to use contains correctly. Thank you so much for your help!
